We can now create the replica link between the two pods.
Log in to the local FlashArray GUI, and go to Protection --> ActiveDR. Click on the plus sign on the top right corner of the Pod Replica Links panel to bring up the following dialog.
When the Create button is clicked, ActiveDR automatically begins the initial synchronization process by using Purity's asynchronous snapshot-based replication engine called baselining and as shown by the Status column.
Once baselining is complete, ActiveDR automatically transitions to its normal replicating mode where low RPO continuous replication is used.
The Reovery Point column displays the timestamp of the most recent changes that have been successfully replicated to the remote pod and represents the recovery point in case the remote pod is promoted.
The Lag column shows the amount of time the DR pod is behind PROD pod.
Here's how we create a replica link using the CLI command.
pureuser@sn1-x70r2-e03-27> purepod replica-link create oraprd12-pod-x --remote-pod oraprd12-pod-dr-x --remote sn1-x70r3-e03-30
Name Direction Remote Pod Remote Status Recovery Point Lag
oraprd12-pod --> oraprd12-pod-dr sn1-x70r3-e03-30 baselining -
pureuser@sn1-x70r2-e03-27> purepod replica-link list
Name Direction Remote Pod Remote Status Recovery Point Lag
oraprd12-pod --> oraprd12-pod-dr sn1-x70r3-e03-30 replicating 2020-10-24 02:08:16 PDT 1s
After a replica link is created, only new volumes can be created inside a pod, existing volumes can no longer be moved into the pod.
